Abstract A condensation reaction involving a free base tetraarylporphyrin‐2,3‐dione, a macrocyclic compound containing a 1,10‐phenanthroline‐5,6‐dione and a 1,2,4,5‐tetraminobenzene as a linker affords the corresponding conjugate in good yield. The porphyrin ring and the phenanthroline fragment of the other ring are connected in such a way that mutual rotation between these two groups is prohibited. Metallation of the porphyrinic site affords the corresponding zinc complex. By reacting this zinc porphyrin with copper(I), followed by the addition of the bidentate chelate 2,9‐bis( p ‐anisyl)‐1,10‐phenanthroline, the threading reaction leading to the corresponding pseudorotaxane takes place quantitatively.
